Global Warming 

Introduction

The most important issue in the current global environment is global warming. According to Kraaijenbrink, Bierkens, Lutz &Immerzeel (2017), the average temperature of planet Earth is increasing at a continuous rate. As a result of this, the polar ice tends to melt, the natural ecosystem is getting destroyed, and mankind is suffering from the loss of fresh water and increased pollution issues. In this report, the argument is based on the consideration, as for why global warming is an important issue. In this context, the triggering factors responsible for global warming include human factors. This argument could be supported with the discussion, for, control measures can be adopted for minimizing global warming. As a matter of fact, it will shed light on the negative consequences that planet Earth is going to face, if global warming remains a persistent problem (Yan et al., 2016).

Scope of this report

In this report, the focus in on arguments,for the factors that are responsible for global warming. In this consideration, first we will discuss, why this topic is of significant interest in context of global environment and then detailing the trigger factors responsible for the same. In the next section, we will argue, the impact of global warming, if it remains uncontrolled. Lastly, we will discuss the recommendation measures that can help in controlling global warming. Down the line, the report will be concluded with a summary.

Argument: Why global warming is important

Global warming holds a significant impact on this society, climate, and health. The primary impact of global warming is climate change, which has multifold negative outcomes on the biological, physical, and human systems. Due to global warming, the temperature of the planet has increased by 1.1 degrees Celsius since 1750, which is expected to even rise by 2.7 degrees Celsius by the end of the present century (Tavoni et al., 2015). It is necesary to take immediate action towards reducing global warming emissions, the issue is believed to grow intensely in the near future. With an increase in global warming, there is an increased risk of accelerating the rate of sea level rise because of the melting of ice mass present at poles (Kraaijenbrink, Bierkens, Lutz &Immerzeel, 2017). The increase in sea level eventually raises the risk of flooding to the low lying coastal communities. According to reports, the average global sea level has increased by 8 inches since the year 1880. However, this increased level is much faster on the Gulf of Mexico and the US East coast (Yao, Xue, He, Bao, Xie&Ge, 2017). Furthermore, global warming also increases the temperature in the summer and spring which results in a hotter and drier forest for a longer time. This situation enhances the risk for the ignition and spread of wildfires. Global warming is also related to frequent and severe heat waves from the past 60 years (Li, Qiao, & Yu, 2015). These heat waves cause serious health issues such as heat stroke, exhaustion, and dehydration. Scientists are expecting the weather to become worse in the coming years if global warming is not controlled. Down the line, this rising temperature encourages an intense allergy environment, insect-borne diseases, severe droughts, deforestation, heavier rainstorm, and air pollution. All of these changes in the climatic condition results in serious and costly health risk to the public (Li, Qiao& Yu, 2015). It is important to identify the causes of global warming and accordingly regulate our activities which maximize the greenhouse effect and endangering the survival of human beings, flora, and fauna.

Current issues that trigger global warming

There are several issues that trigger global warming over the past few years. According to the Intergovernmental panel on climate change (IPCC) report, human activities of the major reason to adversely affect the environment through global warming. First, the transition of the farming based economy towards industrialization is regarded as the earliest cause. Research suggests that global warming started to increase since the mid-nineteenth century when the Industrial Revolution commenced (O'Neill, Williams, Kurz, Wiersma, &Boykoff, 2015). Deforestation is also considered a major reason for global warming. According to reports, 39 million acres of tree cover loss was identified in 2017. Overuse of electricity, especially from fossil fuels also leads to global warming. The United States alone contributes 28% greenhouse gas through electricity generation. An increase in the number of vehicles (in air, water, and road) which runs through food in fields such as gasoline also contributes to greenhouse gas. The burning of fossil fuels contributes to the emission of carbon dioxide and other pollutants (Miller et al., 2017). In addition to this certain agricultural as well as waste management process also aggravate this problem by releasing gases such as nitrous oxide and methane. Increasing the livestock farming of sheep and cows results in the production of a large amount of methane with their food digestion. Using fertilizers in the agricultural sector also emits greenhouse gases like is nitrous oxide. Expansion of residential and commercial building results to deforestation which consequently triggers global warming. According to IPCC report, the contribution of the economic sectors like energy supply (25.9%), transport (13.1%), residential and commercial building (7.9%), industry (19.4%), agriculture (13.5%), forestry (17.4%), and waste management (2.8%) towards global warming (Yan et al., 2016; Miller et al., 2017).

What if, these factors are not controlled?

Presently, global warming is considered as an increasingly urgent problem. If the remaining fossil fuels available in the ground will be further used by the people, then the Earth's climate will reach beyond tipping points. Due to global warming, the afferent sea level will be rising. This will be mediated by the declining Arctic sea ice, and thus the total percentage of freshwater will also be decreasing (Pardo, Moral, Aguilera, &del Prado, 2015). ‏Other potential impact of global warming are reflective in terms of changes in current waves of the ocean, irregularities in the pattern of airflow, and change in the hydrological cycle. Thus, it affects the animal and plants of the concerned region will be affected and thus will impact human beings.

Global warming also increases the trait of heat waves, tropical cyclone, and intense droughts. As a result, the extreme conditions ‏it effects the balance of the natural ecosystem. For example, it destroys the natural habitat, forces animals for habitat migration, results into the extinction of many species, and convert many of the cryosphere and ocean region unfit for selecting as habitat. Thus, the change in weather condition is likely to affect the health aspects of the community member. Importantly, it is also argued that the majority of the effects in the atmosphere and natural ecosystem is irreversible. Furthermore, these changes impact the socio-biological system. Ultimately, health consideration, food availability, balance in the natural biological system are likely to be affected to a significant extent.

Necessary steps required to control global warming

Major steps such as reducing deforestation and increasing plantation can control global warming. However, strong policy measures are required to minimize human contribution. For example, the US and Canada have implemented regulatory frameworks to reduce carbon footprint. Likewise, Environment control agency has argued to control pollutant release into water bodies, and reduced consideration for opting vehicles which causes less emission (Landrigan et al., 2018). Similarly, avoiding the use of aerosols, fireworks, and reduced usage of substances that causes emission will be pivotal in controlling pollution. This requires implementing policies such as cleaner production, green synthesis, and less use of fossil fuels as a source of energy. As a matter of fact, the Industries are required to control the release of waste and pollutants to get approval from government agencies, in majorities of developed and developing nations.

Urbanization and establishment of industrial sectors are also known to contribute to global warming. Strong regulation is thus needed to control these triggering factors. Similarly, from an individual perspective, the use of renewable resources, minimization of waste release, and responsible act are desired to reduce the extreme of global warming (Pardo, et al., 2015). This also include reducing the vehicle ride, using fuel-efficient vehicles, and invest in energy efficient appliances. More importantly, planting trees is the best possible opportunity which can be contributed by community members, in conjunction with measures to control global warming. The recommended step also emphasise the need for promoting awareness, communicating the control measures to community members, educating them to contribute to this sustainable issue (Ascione, Bianco, De Masi, Mauro &Vanoli, 2017).

Conclusion

In summary, the present report discusses global warming as one of the most important issues in the global environment. The underlying factors that trigger this problem include improper waste management from various sources, increased urbanization and deforestation, and increase the level of pollution. As a result of which, global warming destroys the natural ecosystem as well as reduces the level of freshwater. However, the effort for reducing pollution and waste can offer a sustainable solution in reducing the global warming issues. With these learning, it is realized that control of these factors is of high importance for the benefit of mankind.
